I had the 3rd of a series of Skype chats today, as I am completing some work to author a resource pack to support teachers in using the game with students.

From the website:

The game is called Ice Flows - because it does! Ice behaves like a
fluid and flows due to gravity, much like a blob of treacle does, though
a bit slower. Snow falls on the top of the ice sheet, and ice is lost at the edges and underneath through iceberg calving and melting. If the inputs and outputs are equal, the ice sheet
finds a balance – a “happy place” (or more scientifically, an
equilibrium state), where the ice flows at a rate to balance these
inputs and outputs.The game is based on a simple ice sheet model which represents the
way in which ice flows, and how that flow is altered by changes in the
surrounding environment. Computer-based ice sheet simulation models are
used by scientists to both understand how the ice behaves and to make
projections for future behaviour.

Ice flows slowly, from a few metres per year, to several metres per
day. In the game, time and space are modified to make the game
playable.

The game would take a very long time to play if we didn’t speed up
time, the game time for one level represents thousands of years, though
changes in ice sheets over decades can cause a significant contribution to sea level change.If the height and length of the ice sheet were representative of the real ice sheet , you would need to line up a few hundred phones in order to see the whole ice sheet. Hence, the ice sheet
has been stretched in height in comparison to its length. Each
profile represents about 1500 kilometres in length, and about 4000
metres in height.

This year is turning into a bumper year for ice bergs apparently, with reports of a large number in the sea off the coast of Canada, and into the North Atlantic.
